Risk Level: HIGH
Full Analysis
HIGH W007: Insecure credential handling detected in skill instructions.
- Insecure credential handling detected (high risk: 0.90). The prompt includes commands that embed plaintext secrets (e.g., fill @e2 "password123", set credentials user pass, set headers '{"X-Key":"v"}' and saving/loading auth.json), so an agent following it would likely need to output secret values verbatim, creating exfiltration risk.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 1.00). The skill's core workflow (SKILL.md) explicitly navigates to arbitrary URLs with "agent-browser open " and ingests page content via "agent-browser snapshot -i", "agent-browser get text/get html", and "agent-browser eval", meaning it fetches untrusted public web pages and uses their content to drive interactions and decisions.
